Mr. P. also presented a specimen of African Cotton. 



It is the produce of a large tree, and is found on the ground 

 when the seed vessels drop. Mr. Teschemacher observed that 

 the seed indicated the tree to be of the Malvaceous family ; the 

 staple, although fine and silky, was very short and weak. 



Mr. Teschemacher reported on some papers in the Acta 

 Curiosorum, presented by Dr. A. Gray, on the system of 

 Crystallography, by M. L. Frankenheim. 



On the Jura Limestone, of Kurkowitz, by E. F. Glocken. 



Mr. T. observed that it contained a minute and excellent detail 

 of the locality, and that it was remarkable for giving an account, 

 with a plate, of dendritic deposits of maganese, in sand stone, ex- 

 actly resembling those presented lately to this Society by G. B. 

 Emerson, Esq., which were obtained in digging a well at Newton, 

 in this vicinity, and on which Mr. T. made a report. The star- 

 like appearances, and the lines exhibited in the plate, might be sup- 

 posed to have been copied from those found at Newton. The 

 writer of the paper hints at the possibility of their being produced 

 by electricity. 



The only fossil shell he found was a species of aplychus. 



Dr. Cabot stated, that he had lately found in the market 

 a specimen of what he considered to be the common Amer- 

 ican Deer, Cervus Virginianus, but possessing palmated 

 horns of large size, of which he exhibited a sketch. 



He had not found this anomaly anywhere described, and sug- 

 gested that their occurrence in this instance might serve to indicate 

 a variety.
